CONVERTIBLE TONGS OR IPLIERS.

Specification of Letters Patent.

Patented Mar. '7, 1916.

Application filed January 5, 1916. Serial No. 70,466.

To all whom it may concern:

Be it known that I, JOHN DRAGUN, a subject of-the Emperor of Austria-Hungary, residing at Vilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Convertible Tongs or Pliers, of which the following is a specification.

This invention relates to certain new and useful improvements in convertible tongs or pliers.

The primary object of this invention is the provision of a plier or tong structure having a readily convertible jaw arrangement for operating upon either plane or curved surfaces.

A further object of the invention is the provision of a pair of tongs having shiftable 7 jaw members presenting different forms of engaging surfaces at the different angles of adjustment thereof for accommodating the device for employment with work having surfaces of different forms.

A still further object is the provision of a pair of tongs that is easy and inexpensive to manufacture but which is highly efficient in its employment either as a pipe tongs for engaging curved or cylindrical objects or as a pair of pliers in its usual uses such as grasping flat-sided objects.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawing forming a part of this application and in which like designating pivot pin 12 in substantially the usual man-- nor, the said handles having a bifurcated jaw shank 13 and 14 respectively positioned opposite each other and adapted to be brought into substantial contact with each other when the handles are closed together. The said jaw shanks are bifurcated having ceiving pivot pins 16 upon which convertible jaws 17 are swingingly mounted. These jaws 17 are substantially right-angular in form, and each has a leg member 18 that is pivotally mounted upon the afore-mentioned pins 16 between the shank sides 15 substantiallymidway of the length of the said legs 18 and the legs 18 are provided at one end with inclined faces 19 upon one side and with serrated engaging faces 20 upon the opposite sides. A projecting foot 21 is provided upon each of the legs 18 at the end thereof opposite its inclined end 19. The feet 21 are provided with transverse grooved faces 22 adjacent the fiat sides 23 of the legs 18. The jaws 17 are adapted to be swung upon the pins 16 for arranging the face 20 oppositely positioned for employing the device as pliers as illus trated in Fig. 1 of the drawings, and at which time the shoulders 24: of the feet 21 engage the adjacent sides of the mounting shank for preventing swinging movement of the jaws. The jaws 17 may be swung to their positions illustrated in Fig. 2 when desired for engagement with a curved surface such as the pipe 25. In this arrangecrums thereby forcing the feet and leg surfaces in firm engagement with the pipe. A serviceable and inexpensive tool is thus arranged which may be employed either as a pliers upon plane surfaces or as a pipe tongs in connection with pipes or cylin drical work.

While the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that minor their opposite sides 15 perforated for rechangesmay be made therein Without de- 7 parting from the spirit and scope of the invention as claimed.

lVhat I claim as new is 1- 1. A device of, the class described comprising handles pivotally connected together and provided with extended bifurcated jaw shanks, having inwardly arranged sockets opening between the said shanks, pivot pins connecting the bifurcations of the said shanks, substantially right angularly shaped jaws pivotally mounted upon the said pins and comprising leg portions tapered at one end with oblique faces at one side and rough surface-engaging faces upon the opposite side thereof and angularly projecting feet at the opposite ends of the said legs having shank-engaging side shoulders and grooved faces adjacent the side legs.

2. A device of the class described comprising handles pivotally connected together Copies of this patent may be obtained for and having extended bifurcated jaw shanks, provided with inwardly arranged sockets opening between the said shanks, pivot pins connecting the bifurcations of the said shanks, substantially right-angular shaped jaws pivotally mounted upon the said pins and comprising leg portions tapered at one end with oblique faces at one side and rough surface-engaging. faces upon the opposite side thereof and angularly-projecting feet at the opposite ends of the said legs having shank-engaging side shoulders and grooved faces adjacent the said legs, the said tapered ends of the jaws being'received within the said sockets when the jaws are arranged for gripping curved surfaces and with the feet of the jaws in substantial alineinent with the handles.

In testimony whereof I affix my signature.

JOHN DRAGUN.
